This is not a prediction, but a statement. The idea I was trying to
express is that platform data is needed for legacy boards, those that
predate device tree and/or ACPI support. Therefore there will be no
new users of it appearing in the kernel, as we will not accept a new
board/architecture it using wither ACPI or DT.
